Getting a great night's sleep is not a luxury — it's something all of us need. Without it, we just can't function at our best, and we feel tired and restless. Of course, the duvet you choose is crucial to achieving this great night's sleep, and the beautiful feeling of refreshment and rejuvenation that follows.

We tend to think about togs when we choose a duvet, and we certainly need to make sure we have the right duvet for the climate or for the time of year. But what about duvet sizes? Isn't this important too?

Yes, it certainly is. There is much more to selecting the right duvet than simply choosing a single duvet for a single bed, a double duvet for a double bed, or perhaps a king size duvet for an extra-large bed. In this article, we are going to look at exactly how to find the right size duvet for your bed.

Getting Duvet Sizes Right

Duvet sizes are important for two reasons: aesthetics and comfort.

From the aesthetic point of view, your bed simply is not going to look right without a correctly sized duvet. Obviously, a single duvet is going to look odd and out of place on a double bed, and vice versa, but there are more factors to consider. The specific size of the bed is important here — bed sizes extend far beyond the overly simple classification of single and double. Select the wrong one and your bed — and even your entire bedroom — will look a little off.

From the comfort point of view, you need a duvet that covers the sleeper or sleepers without dragging on the floor or overwhelming the bed. This is only achievable with the right size duvet for your mattress.

Duvet Sizes

There are lots of different sizes of duvet available to consumers, and the level of choice can become a little overwhelming at times. However, the duvet size can be ascertained quickly and easily.

To find which duvet size you need for your bed, measure the size of the mattress itself. Bear in mind that the size of the mattress will not be the same as the dimensions of the duvet that will fit it. You will also need to factor in the thickness of the mattress itself — for thicker mattresses, a slightly wider and longer duvet will be required.

To gain a rough idea, measure the length and width of the mattress. Next, measure the thickness of the mattress, and add this third measurement to the values for the length and the width. 

You can find out more about these crucial measurements and the duvet size categories they represent below.

Single Duvet Sizes

single duvet is designed to fit on a single bed with a single mattress, and is generally suitable to accommodate just one sleeper.

The dimensions of a single duvet will be around 135 by 200 cm, or 53 by 75 inches.

Double Duvet Sizes

double duvet is the next size up, and it is designed to accommodate up to two sleepers on a standard double bed.

The dimensions of a double duvet will be around 200 by 200 cm, or 78 by 78 inches, giving the duvet a square shape.
